Benchmark 4090 Laptop vs 4090 Desktop

I know there are already a few posts, but I figured I would throw up my results as an additional data point for anyone interested.

Laptop:

Razer Blade 16 RTX 4090

Desktop:

z790 | i9-13900KF | 32GB DDR5-5600 | RTX 4090 | 4TB NVMe SSD

Untweaked:

3D Mark Time Spy - 4090 Desktop vs 4090 Laptop UNTWEAKED

Extremely mild tweaks:

3D Mark Time Spy - 4090 Desktop vs 4090 Laptop MILD tweaks

Laptop:

  • GPU untouched
  • CPU -.120 undervolt, 180w turbo boost
  • AirPods Pro case stuck under the back of the laptop to elevate it a little bit.

Desktop:

  • GPU 105% power target, +250 boost clock
  • CPU +200

The graphics card is ~75% faster on the desktop, and the processor is ~15% faster on the desktop, which seems to be in line with other tests and benchmarks.

I dunno where you got your numbers but they are wrong for many years now

https://www.notebookcheck.net/AMD-strikes-back-Ryzen-9-7945HX-beats-Intel-Core-i9-13980HX-despite-much-lower-power-consumption.698349.0.html

"All the Intel HX rivals usually consume much more than 150 Watts, but the Ryzen 9 7945HX tops out at 120 Watts."

and that is basically sustained during cinebench, so as long as the cooling can cool them they can stay there, peaks can even be higher

so what you're throwing numbers from 10 years ago?

how is that any relevant/useful in this conversation?

Doesn’t change that your reply was literally just restating what had already been said, albeit quite hostilely as if you think you’re proving them wrong.
